This invention relates to a fruit jar glass lid tightener and has forits prime ob ect to provide a structure of this nature which is simple,inexpensive to manufacture, strong and durable, easy to manipulate,thoroughly eflicient and reliable in use and otherwise well adapted tothe purpose for which it'is designed.

With the above and numerous other objects in view as will appear as thedescription proceeds, the invention resides in certain novel features ofconstruction, in the combination and arrangement of parts as-will behereinafter more fully described and claimed.

In the drawings:

Figure 1 is a top plan view of the structure embodying the features ofmy invention.

Figure 2 is a side elevation thereof.

Figure 3 is a vertical section therethrough taken substantially on theline 33 of Figure 1.

Figure 4 is a band.

Figure 5 is a perspective View of the thumb screw.

Figure 6 is a perspective view of the cap. Figure 7 is a perspectiveview of the bar, and

Figure 8 is a perspective view ofone of the straps.

Referring to the drawings in detail it will be seen that numeral 5denotes the neck of a glass jar, numeral 6 the rubber gasket and numeral7 the glass lid. These parts just de scribed are conventional.

Numeral 8 denotes a bar longer than the diameter of the neck 5 and theends of which are slotted as at 9. Numerals 10 denote straps twisted atright angles intermediate their ends and the upper ends are pivoted asat 11 in the slots 9. On the lower ends of the straps are pins 12 whichincline upwardly and inwardly. Numeral 14 denotes an inverted saucershape cap of resilient sheet metal or the like to be set on top of thelid 7 perspective view of the split and in the center of this cap 14there is loosely swiveled the lower end of a thumb screw 15 which isthreaded through a central opening in the bar 8. Numeral 16 denotes asplit band 60 having apertured cars 17 projecting out 1932. Serial No.602,022.

wardly from the ends thereof so that a bolt 18 may be engaged therewithfor tightening the band about the neck 5 as shown in Figures 2 and 3.This band is provided with diametrically opposed apertures 19 into whichextends the pins 12.

From the above detailed description it will be seen that after the bandhas been assembled about the neck the other parts may be quickly andeasily assembled and the thumb screw manipulated to press the cap 14downwardly against the lid 7 to tightly seal the lid.

It is thought that the construction, operation, utility and advantagesof thisinvention will now be clearly understood withouta more detaileddescription thereof.

It is apparent that changes in the details of construction may beresorted to without departing from the spirit or scope of the inventionas hereinafter claimed or sacrificing any of its advantages.

Having thus described my invention, what I claim as new is:

In a structure of the class described, a split band, means for holdingthe split band about the neck of a jar, said band being provided atopposite points with openings inclining upwardly and inwardly, a bar, onthe ends of the bar and having their free ends provided with inwardlyand upwardly inclined pins to engage in the openings, a thumb screwthreaded through the bar, and a lid engaging member swiveled on the endof the thumb screw.

In testimony whereof I afiix my signature.

ADOLPH WITTWER.
